INCANDESCENT WICK-BURNER.

Application filed January 2, 1909. Serial No. 470,390.

To all whom it may concern:

Be it known that` l, Josnrrr HERZOG, of the city and county oi Philadelphia, State of Pennsylvania, a subject oi the Emperor oi Austria-Hungary, have invented a new and useful Improvement in Incandescent 'lllick-llurners, of which the following is a specification.

Figure 1 is a section of my improved burner; Fig. 2 is a plan view of the spreader and Fig. S is a modiiicntion of the burner head.

My invention relates to wick lamps, and is designed to providean improved burner which will enable a wick burning lamp to be used with a mantle, and to produce a flame from the burner of such a character as to raise the mantle to incandescence.

The invention consists in providing a device tori changing 'the yellow flame of the ordinary wick lamp to a blue flame, and to prevent the burner from smoking by supi plying a sufficient quantityolFl air to enable complete combustion to take place.

Referring to the drawings, Q represents the wick tube, which is annular in form and tapered toward its top. rlhe inner wall of the wick tube extends slightly above the outer wall 3, thus enabling the wick, which is circularto be cut frusto-conical in shape. Outside of the wick tube 'is the annular air passage Ll having a row of outer holes or air ports 5 through which air is drawn in to cool the burner and prevent heat passing into the font. The wick tube 2 is provided at one side with a slot 6 which supplies air to the inside of the burner through the passage 7. The outer wall of the wick tube 2 has an outwardly flaring 'top 8 which is preferably integral with the side wall.

l) is a spreader suitably mounted on the inner wall ot' the wick tube 2 and which preferably has two plates each provided with a row ot' holes, one row being staggered slightly relatively to the other as shown in llig. so that air supplied to the inner sides of the llame is given ra swirling mo` tion.

1U is the burner head which has an inwardly flaring top 1l and an annular shelf or deck l2 located on its inner surface and below said top, and having pertorations l?) therein.

1l is an incandescent mantle which is suspended from the support 15.

16 is the globe whichis positioned over the burner head in the ordinary manner.

YVhen the lamp is lighted, theI main supply of air enters inside of the through the slot G in the air passage 7 The suction caused by the flame induces a strong draft and upon striking the spreaders the air forces the flame outwardly and by pass ing through the spreaders a whirling motion is imparted so that the airv and the gas are more thoroughly mixed and a more perfect combustion results.

The secondary supply of air enters through the air ports 5 and passes through an annular air passage l, and is checked in its velocity by the outwardly flaring top 8 of the wall A portion of this supply is drawn through the opening 17-into contact with the llame and a portion passes upwardly through the perforations 13 of the deck 12 into the chamber 1S from which it comes in turn in contact with the flame'.

The main air supply passing through the slots 6 and passage 7 drives the llame out-y wardly, while the secondary air supply eirtering through the ports 5 and annular passage 4 operates to press inwardly on the llame.` This operates to make theiwall of flame very thin and enables la more perfect mixture. The outwardly tial-ing 'top 8 prevents the too rapid feed of the air to the base oi the llame, and the opening17 and chamber 18 enable a'more uniform distribution of the secondary supply of air to the llame. This distribution of the secondary supply of air also prevents any yellow points of llame from striking the mantle, which would cause sooting ot' the mantle and smoking of the lamp. 'The deck 12 is arranged so as to be in line with the lower' surfaces of the lower disks of the vspreaders 9 so that if the lamp ,is turned too high the air sup'- ply entering` through the opening 17 will be cut ott sutliciently to extinguish the' lamp.

ln 3 l show a plurality of air chainbers, so that where conditions require a greater' distribution of air lto the outside ot' the llame this may be satisfactorily accomplished. In this figure, ff) indicates the source of the additional air supply.

lt will be seen by those skilled in the art sev that many changes may be made in my burner without depart-ing from my invention, since What I claim is:

1. In an incandescent wick burner the combination of the outer wall of the Wick tube with an outwardly flaring top, and a hollow burner head located thereabove and having a perforated annular deck therein and an inwardly projecting top above said annular deck; substantially as described.

2. An incandescent Wick burner having a spreader located above the wick, and a hollow burner head having on its inner surface a perforated deck, said deck being arranged in line with 'the under surface of the spreader; substantially as described.

3. In an incandescent wick burner a hollow burner head having a plurality of air chambers, each of the said chambers having 20' JOSEPH HERZOG.
